"Symantec's product management team "has only received a handful of reports concerning this type of behaviour and we believe this to be an extremely rare occurrence", a spokeswoman told us. "The product is working as expected for the overwhelming majority of Norton Internet Security 2003 users."

This is not true. If you use a pre-check like Mailwasher or Intervene you will easily convert ALL your email to "Symantec Email Proxy deleted the following email message." The same bug has affected Norton AntiVirus 2003 and Symantec knows this from the day it was released.
